CENTRIFU'GAL Oum@ Device,

Specification of Letters Patent.

` Patented March l2, 1907.

Application filed August 7,1905. Serial No. 273.003.

To n/Z/f wiz/ont it mld/y concern: Be it kownthat I, HENRY G. REIs'r, a citizen of the United States, residing at Schenectady, county of Schenectady, State and relates particularly to improvements 1n the device illustrated in my Patent No.

In said atent a vertical-shaft dytating oil-receptacle beneath the lower bearing and a pipe leading from this receptacle to the upper bearings. As the receptacle revolves oil is forced into and through the pipe.

The object of the present invention is to provide a centrifugal oil-distributer in a machine having a revoluble art, which distributer shall be ositive an effective in its action, simple -1n construction, requiring but little alteration` in the machine to which it is applied, and which shall embody no movable parts without the frame of the machine.v To the above ends I have made the main oil-re,- ceptacle stationary and rovided one ormore vanes secured to the sha t and projecting into the receptacle. :As the shaft revolves -the vanes set the oil in motion and positively force it into the discharge-pipeleading to the oint' to which the lubricant is tobe transerred. The oil-receptacle may thus consist simply of a chamber located in the main frame of the machine.

My present invention will be more fully understood in connection with the following detailed description thereof as embodied in a preferred form.

In the accompanying drawings,vI"igure v shows a dynamo-electric machine, partly in side elevation and partly in cross-section, to

which my invention is applied. Fig. 2 is a cross-section through the main oil-chamber, and Fig. 3 is a detail view'of the ring carryin the rotating vanes.

leference being had tothe drawings, 1 indicates a dynamo-electric machine having'a vertical shaft 2, supported at its lower end u on a thrust-bearing 3 and held in vertical a inement by means of upper and lower side bearings 4 and 5, respectively. Surrounding and concentric with the thrust-bearing or a ortion thereof is a'chamber 6, preferably ormed in the main frame, as shown. This forms the main oil-chamber, to which oil -is supplied iirst through transverse passages 7 in the thrust-bearing and afterward from bearin s 4 and 5 as the oil passes .down throng these latter bearings. Oil is originally supplied to the bearings, and the supply is maintained through a small stand-pipe 8,

which communicates with a central o ening- 10 in the plates of the thrust-bearing t ough pf ssage 9. The pipe 11 connects a pair of y assagesf12 and 13, formed in the wall sur- '.ounding the chamber 6, with the oil-chamber 14 associated with the upper bearing 4. The movable part of the 'pump or oil-distributer consists of a series of vanes 15, radially arranged on the under side of a ring 16. The ring 16 is rigidly secured to the shaft of the machine either directly or, as shown,'by be- ,ing Imounted upon the revoluble member 17 of the thrust-bearing. A clearance is maintained between the member 18, which forms the upper wall ofthe chamber 6, and the top of the ring 16, and a clearance is also maintained between the outer wall 19 of the cham-v ber and the outer edges of the ring and vanes, so that oil may pass from the bearing 5 back into the oil-chamber and beneath the ring 16.

When the chamber is filled with oil and the shaft is set in rotation, each ofthe vanes carries a portion of the oil before it, and as the speed of the machine increases the centrifugal force exerted upon these portionsof oil is sufficient to carry them outwardly as they approach the entrances to the passages 12 or 13 and cause a stream of oil to flow throughl the pipe 11 to the upper bearing. The oil then after passing down through the upper bearing proceedsl through thev passage 20 to the lower. side bearing 5 and thence back again to the main oil-chamber.

Two passage-ways 12 and 13 are provided in order thatthe lubricating device mayopverate equally wellfor either direction of rotation of the machine.' The axes of these passage-ways referably diverge from each other, so as to be substantially tangent to the inner wall of the chamber 6 at two separated points, 'thereby providing a path which the rotating oil tends to follow when the direcchine is required an extremelysimple and cheap oil-distributing device is produced, and by reason of the inclosure of the rotating part within the main structure all danger of injuryvthereto by contact with external objects is obviated.,

While I have illustrated and described the resent invention in the ,best form noW noWn to me, I do not desire to be limitedto the particular form shown except to the eX- tent indicated in theaccompanying claims, since in its broader aspects the present invention may be embodiedfin various other forms. v

,What I claim' as new, and desire to secure by Letters Patent of the United States, is-l 1, In a machine'having 'a rotating shaft and a bearing fo'r said shaft, a centrifu al oildistributer comprising anoil-receptac e's'ubstantially concentric with said bearing and receiving oil therefrom,l a 'discliarge-pipeleading to a part to belubricatedand con neeted to a passage-Way in thev Wall of said receptacle, land a vane secured to said shaft and extending into said receptacle for forcing oill ,intol said passage-Way, said vane having i lts face arranged transversely to the d1rec tion of motionA 2. `'In a machine. having a rotating shaft and a bearing for said shaft, a' centrifu al oildistributer comprising an oil-receptac e sur-l y rounding said 'bearing and receivingr oil therefrom, a radial vane secured to said-shaft and v -projecting into said receptacle, said vane avlng its facearranged transversely to the directlon of motion, and a discharge-pme leading to a partto be lubricated ard con- .ne'cted to a passage-Way located in the wall of said receptacle and arranged in the planeef rotation of said vane. l y

3. In a machine having a rotating .shaft and a4 bearing for saidg' shaft, a centrifugal oil-distributer comprisin an oil-receptacle surrounding said bearing and receiving oil therefrom, a radial vane secured to said shaft and rejecting across said. receptacle, said vane aving its; face arranged transversely to the direction of motion, anda discharge-pipe leading to a part to be lubricated and connected to a passage-Way located in the' Wall of said receptacle and arranged in the plane of rotation of said vane and at an angle to the radius passingfrom the axis of said shaft tothe passage-way.

4. In a machine having a rotatingshaft and a bearing for said shaft, a centrifugal oildistribut'er comprising a receptacle concen tric with said bearing `and receiving oiltherefrom, a discharge-pipe leading `from a pasl sage-Way in the Wall of said receptacle to a part to be lubricated, and a plurality of vanes secured to ysaid shaft and extendingl across sald receptacle, sald vanes being ar-v ranged With their faces transverse-to the direction of motion.

5. In a machine having a rotating shaft and a thrust and a side bearing lfor said shaft, a lcentrifugal oil-distributer comprising an eil-receptacle arranged at one end of vsaid sidepbearing and surrounding said 'thrustbearing, a' dischargapipe leading from a passage-Way in said receptacle to a point above said side bearing, and ayane secured tosaid shaft and extending across said receptacle.

6. In a machine having a vertical rotary shaft with upper and lower bearings including a lower side bearing and a lower thrustbearing, a centrifugal voil-.distributer ceniprising an oil-receptacle arranged at the oWer end of said lower-side bearii g and con* t centric with said tl1rust-bearing,a dischargepipe leading from a passage-Way in the Wall of said receptacle to said upper bearing, and' a vane 0r Vanes secured to said shaft and eX- tendmg'a'cross said receptacle.
